Hi Dotty
I had this after a virus/ really bad cold thing last February. I was unwell for weeks and weeks with it, but my sinus on one side didn't get back to normal until August, and I ended up on Avamys a steroid nasal spray which did the job. If you have post nasal drip, that also causes a cough. I also worried and worried and ended up at the doctor but for me it was post viral fatigue (which took 6 weeks to go) and a sensitivity (irritation / inflammation cycle) which lingered on right side due to that sinus probably being narrower. Anyway, I came on to say that these things can take a lot longer to resolve than what the NHS says, particularly as we get older.
Also re the cough, I've had coughs after bugs which have lasted 4-6 weeks. If you've had a bug and have a cough it's far less likely to be anything bad than if you are well and develop a cough out of nowhere. But yep, I'm the same and automatically talk myself into lung cancer too.
Don't forget though that in meno , all our mucous membranes are drier, and that includes those in the respiratory tract and lungs. Everytime I try and stop my estrogel , my throat dries out and I get a throat cough especially on waking. So things can also take longer from that perspective too.
Finally, also a thumbs up for the Neilmed sinus rinse. But do consider short term use of a steroid spray if the sinuses don't settle, as it really does knock the irritation / inflammation (which becomes a vicious cycle) on its head. I no longer use mine now as its done its job. Don't get mixed the steroid one up with the antihistamine drying type one as I did try that first and it made it worse. The one you'd need you will need to get from the GP on prescription.
